From the curve given we can see that the graph that shows a function where f(2)= 4 is Graph A.
Equation of quadratic graph
A quadratic graph is in form of a parabola opened upward or downward.
According to the question, we are to select a graph that has a coordinate (2, 4) on its curve.
To determine thus, we will locate the value of 2 on the x-axis and value of 4 on the y-intercept and trace whether the intersecting point is on the curve.
